Solo travelling was how I formed one of my most salient memories of the "moat of low status", to wit: going to Japan in 2011. Japan is an advanced G7 country, but unlike most of the rest, very few people there speak or understand English. So I was put in the position of having to get by with my shitty Japanese, or attempt to communicate even more futilely with the locals in English and seem like an even bigger, more clueless asshole. I think I gained more levels of Japanese in those two weeks than I did in two years of university education.
